Description

Technical Field

[0001] The utility model belongs to a desk, and in particular relates to a student desk which can correct sitting posture. Background Art

[0002] Desks are basic facilities for students to study, and most of the students' study time is spent on desks. Nowadays, hunchbacks and myopia are quite serious among primary and secondary school students. The root cause is that they do not develop the correct sitting posture when reading and writing. Unreasonable desk and chair design and arrangement are not conducive to the students' bone development. Long-term use may even cause deformation of the cervical spine, spine, lumbar spine, etc., and may also cause myopia in students, which seriously endangers their health. Therefore, it is very necessary to design a desk that can correct students' sitting posture.

[0003] Current sitting posture correctors only focus on the correction of the position of the shoulders and the position of the head, while ignoring the correction of the waist and leg postures. For example, the patent with patent number CN202221211848.5 discloses a desk for correcting students' sitting postures, including adjustable desk legs and a desk frame fixedly installed on the upper end of the adjustable desk legs, a desk top is installed on the desk frame, and a sitting posture correction mechanism is provided on the desk top, which can correct the students' sitting postures, keeping the students' chests one fist away from the desk and their eyes one foot away from the desk. Although the students' heads and chests are kept at an appropriate distance from the desk, due to the lack of support for their waists, they are prone to hunchbacks after sitting for a long time, and there are no restrictions on the position of the students' feet and legs. When the legs are in an improper position, it is easy to cause distortion and deformation between the lower body and the upper body. Therefore, a desk that can correct the students' whole body sitting posture is needed in the prior art. Summary of the invention

[0004] The utility model aims to provide a student desk which can correct the sitting posture, so as to overcome the defect that the student desk in the prior art cannot correct the sitting posture of the whole body.

[0005] The utility model is realized by adopting the following technical solutions:

[0006] A student desk capable of correcting sitting posture comprises table legs, a table box mounted on the table legs and a table top panel mounted on the table box, and also comprises a sitting posture correction guardrail, a waist restraint belt and a foot pad. The sitting posture correction guardrail comprises a fixing clamp, a rotating seat, a locking bolt, a vertical rod and a guardrail cross bar. Two of the fixing clamps are respectively clamped on two sides of the table top. The two rotating seats are respectively rotatably connected to the fixing clamps. The rotating seat is provided with a plug hole and a threaded hole connecting the plug hole. The vertical rod is inserted into the plug hole. The locking bolt is installed in the threaded hole. The guardrail cross bar is fixedly connected between the two vertical rods. The waist restraint belt comprises a belt body, a hook and a length adjustment buckle. Two ends of the belt body are respectively connected to a hook. The length adjustment buckle is arranged on the belt body. A hanging ring is provided on the side of the table box. The hook is connected to the hanging ring. The foot pad is arranged at the bottom of the supporting leg, and a foot cover belt is provided on the foot pad.

[0007] Furthermore, the table legs include an adjusting rod, a sleeve rod, a height adjustment bolt, a support leg and a connecting brace. The adjusting rod is evenly provided with a plurality of adjustment holes. The adjusting rod is inserted into the sleeve rod. The adjusting rod and the sleeve rod are fixedly connected by a height adjustment bolt passing through the adjustment hole. The support leg is fixed to the bottom of the sleeve rod, the connecting brace is connected to the support leg, and the foot pad is fixed to the connecting brace.

[0008] Furthermore, the foot pad has an inclined slope, and a raised friction strip is provided on the slope.

[0009] Furthermore, a bookshelf is fixedly connected to the sleeve rod.

[0010] Furthermore, a soft sheath is provided on the guardrail crossbar.

[0011] Furthermore, a graffiti board is provided at the front end of the desktop panel, the bottom of the graffiti board is movably connected to the desktop panel through a movable hinge, a bottom support plate is fixedly provided at the bottom of the graffiti board, a magnet block is provided at the bottom of the bottom support plate, and an iron sheet that can be adsorbed on the magnet block is fixedly provided on the desktop panel.

[0012] Furthermore, two book page baffles are provided on the bottom support plate.

[0034] The working principle of this utility model:

[0035] Sitting posture correction process: When in use, first adjust the height of the table leg 1 by fixing the height adjustment bolt 13 in the adjustment hole 14, so that the desk height adapts to the student's height, and then fix the sitting posture correction guardrail 4 on the desktop board 3 through the fixing clip 41. After installation, adjust the telescopic height of the vertical rod 44 in the socket 47 through the locking bolt 43, and adjust the vertical rod 44 to maintain a certain inclination angle toward the student through the rotating seat 42, so that the height of the guardrail cross bar 45 is approximately maintained at the height of the student's shoulder, and the straight-line distance from the guardrail cross bar 45 to the front edge of the desktop board 3 is maintained at about one fist. Under the restriction of the sitting posture correction guardrail 4, the student's chest and shoulders are maintained at a distance of one fist from the desktop board 3, and the head position is maintained on the upper part of the guardrail cross bar 45, thereby correcting the posture of the student's head, shoulders and chest. After adjusting the sitting posture correction guardrail 4, wrap the waist restraint belt 5 around the student's waist, and then hang the hooks 52 at both ends of it on the hanging ring 21 of the desk box 2, and then adjust the length according to the student's body shape. The buckle 53 adjusts the use length of the waist restraint belt 5, thereby achieving a pulling force on the student's waist towards the desk, preventing the student's waist from forming a hunched back, and thus achieving the correction of the student's waist sitting posture. Finally, the feet are inserted into the foot straps 61 on the foot pad 6 to prevent the student's feet and legs from moving around, thereby achieving the correction of the sitting posture of the feet and legs; the use principle of the graffiti board 8: when in use, the graffiti board 8 can be flipped on the desktop board 3 and fixed by adsorption by the magnet stone 83 and the iron sheet. When not in use, it can be flipped to the bottom of the desktop board 3 to avoid affecting the line of sight. Students can use watercolor pens to write and draw on the graffiti board 8 to increase the interest of students' learning, and the content written on the graffiti board 8 can be erased by a rag, so as to achieve reuse; the graffiti board 8 realizes the function of a reading rack by setting a book page baffle 82. When in use, open the book, place the opened book on the bottom support plate 81, and lean against the front of the graffiti board 8. The two book page baffles 82 are respectively used to limit the random movement of the two opened pages. After the book is fixed, the student can look straight ahead to read.
